5 Transport and storage

A fitting must be handled, transported and stored with care:
» The fitting must be transported and stored in its protective packaging until it is installed.
The fitting has moving internal parts.
Even packaged fittings should be transported smoothly without any shocks.
caution
In the case of a fitting that can no longer be transported by hand, the lifting gear must be
attached to a suitable position on the housing (branches).
Under no circumstances may the lifting gear be affixed to any attachments (adjusting
caution
screw, handwheel or accessories).
» When the fitting is stored prior to installation, it should be kept in closed rooms and protected against
harmful influences such as dirt, moisture and frost.
» In special cases, the fitting is supplied free of oil, grease or silicone and is marked accordingly. A fitting such
as this must not come into contact with oil/grease/silicone during storage and handling (particularly when
subsequently unpacked).
» A MANKENBERG fitting generally has functional and/or sealing parts made of elastomer materials. These
cannot be stored for an unlimited period.
ISO 2230 describes the storage conditions for elastomers in detail and specifies the
permissible storage period.
Functional and sealing parts must be replaced well before the storage period expires.

MANKENBERG fittings of small and medium nominal diameters are largely made of stainless
steel (high-alloy CrNiMo steel).
If, under exceptional circumstances, fittings are stored in a unpacked state, they must be

protected against ferritic dust to avoid corrosion.
